@freemo what surface is it? Iron?
@freemo so there is a very low temperature. Here we are having one of the warmer winter opening i can remember and very stable weather. No too much wind, south, south-east and sunny sky. But this can not last for longer.
I wish a very happy new year for you and all the QOTO comunity!
@mikelga Thank you, happy holidays and new years to you too!
Metal wouldnt be any colder than plastic, it would just change temperature more quickly. But after a night of cold their temperatures would be the same. Also to get really big crystals youd want it to not be too cold, just barely freezing for an extended period of time. For this reason the plastic likely helped this effect as it insulated slightly from the cold for a little bit allowing the water to cool down more slowly.
